Today when I changed this to
gradSchemes
{
default Gauss linear;
// grad(p) Gauss linear;
// grad(U) Gauss linear;
}
it works. I don't know why and this is strange for me.
I haven't had to set up curl(U).
Very thank you for your ultra fast replay and help.

It seems that settings: default none
in gradSchemes cannot be set up if I want to calculate vorticity
with vorticity utility.
